Hello. I'm new to the group and looking for some expert advice on troubleshooting a brake light issue. The problem is that I have no brake lights with the key off. With the key on I have brake lights but no 3rd brake light. If I squeeze the emergency lever over on my brake controller I have all of my brake lights including the 3rd. Really confused on what would be causing this. I have unplugged the brake controller to see if it was the culprit with no luck. All of the fuses have have been checked as well. I do have voltage to the Grey/Red wire on the brake light switch as well. I have seen this problem on other forums but haven't found a solution. I would appreciate any suggestions I can get.
